The system comprising my improved beverage dispensing apparatus is shown in its "referred form in Fig. 1, in which the refnce characters 10 and 11 designate the beverage containing and storing tanks of a like construction except for such slight modifications as are found necessary in suitably connecting them together with conduits for the circulation of temperature controlling fluid and for conducting the beverages therefrom to the 'd' `ensing unit of the system.

These consist of insulated bevnage tanks 12 and 13, preferably of a metal capable of resisting any acid or other corrosive effect of beverage to be treated and dispensed, and they are preferably, although not necessarily, of cylindrical form and provided with closed bottoms except for the draw-off pipes and they are preferably housed or surrounded by cylindrical containers Lidi, 15 having the walls thickened, if desired, for insulating purposes, as illustrated. They may be conveniently formed of double or spaced apart metallic walls and bottoms with the insulating material interposed as shown in the draw- Any suitable insulating material may be employed and any metal or other suitable material usc-d in forming the walls, which shall be capable of resisting the effect of the heat controlling fluids to be employed in heat treating beverz s. rFliese containers 1-1, 15 with their interior beverage tanks may be supported in any desired manner as upon a iloor or platform indicated at 16, it being desirable that they shall be positioned above the beverage dispensing unit so that the beverage may be ldelivered by gravity to the l'lhen the system is employed for dispensbevera. containing as their chief com ponent fruit juices, orange juice and the like, agitation of the beverage within the tanks 12 and 13 at spaced intervals is desirable and necessary to secure uniformity in the product delivered by the dispensing unit. A convenient means of accomplishing this result is obtained by providing a removable cover 17 which has a peripheral portion adapted to fit over the top of the outer tanks .1&1 and 15 and being adapted also to cover the open top of the beverage tanks 12 and 13 on the interior. The removable cover 17 will be preferably provided with a central bearing portion 18 adapted to have journalled therein a shaft 1) carrying a plurality of spaced apart paddles or stirrers as designated by reference character 20. The latter may of any desired construction to suitably agitato beverages within the tanks 12 and 13 when a rotary movement is imparted thereto through the shaft 19 by means of an electric motor 21, the shaft of which will be directly connected with the shaft 19, preferably to forni a continuation thereof. Instead of the motor 21, obviously, any suitable mechanical device may be employed for operating the stirrer shaft and the stirring elements 2O thereon, but l prefer the use of the electric motor, particularly where fruit juice bever- 'irri ages are to be dispensed bythe apparatus, and

'i The draw-ofiV or dispensingy unitv ofV my beveragey dispensingsystem requires special treatment in lits design for lpurposes of utility as well as' appearance. .The matter of ornamentation or appearance in a dispensing` Y deviceis of prime'importance byreason ofl kthefact thatV such apparatus is commonly view of patrons using the beverages' to be dispensed thereby. The reference charactereO designates generally this unit of my dispensing-system. l prefer vto Vconstruct itso that [it may be'fpositionedupon a tablel or counter,y as indicated "at l1, for convenience inV installr. ing, which dispensingord'rawfoii unit may s l v be detachablyfmountedrr carried upona piate1l2 capable of being. placed uponthe counter or table 41, as illustrated in F ig. 1.

Shownin its assembled'relation with the 'bei'ferage preparing, storage andt'emperature c treating portions Yof my system inFig. 1, the vdetails of my dispensing unitifl() are shown .most clearly. in connectionwith Figs. 2 to 1(7) inclusive.' Beveragesy being' dispensedv from the unit l() of lmy system will preferably, ali though l'not necessarily, be conducted thereto' at substantially the temperatureat which it is `desired to serve the saine. The construction of the draw-olf unit40, however, is such that. temperature control kis l attained while the beverage is within lthis unit ofthe sys? ftein, 'this temperature control being yof ak character that will f permit modifica-tion of maintainthe beveragein a uniform tempera# sired operating period. s Obviously, the" iI1` cliision of temperature controllingmeans in the draw-ott unit 4C()V results in the inclusion of many improved details :of construction in fdeture condition while therein during any "de-`r the (temperature. of tlievbeverage after. it enters the Vdraw-olfl unit 40' ,or the tempera-v ture control apparatus .may be usedvmerely tok vleefy vic'es of this 'character tofinsure that:y the L pa.ti`"onsV will at all timesbe supplied *with beverage at anabsolute uniforinandprede-y termined temperature so necessary tok thesuccessful service of beverages. f

In considering the embodiment of my invention as illustrated iu the drawings, it is of assistance to note that l have used the double headed arrows throughout the said drawings to indicate compartments and passages through which the beverage passes or is contained while the single headed arrows throughout the system indicate compartments and passageways :only accessible to temperature controlling fluid.

In the construction and arrangement of the elements entering into my beverage drawod unit or dispensing urn, and to permit of the quick detachability of all the various parts thereof in contact with the beverage being dispensed, to obtain easy accessibility for sanitary cleaning or cleansing of the apparatus, l prefer to construct the beverage dispensing urn portion of the unit so that the urn or compartment itself` may be easily and quickly detached from its base or support, thus opening the interior of thebeverv age compartment so that the temperature control apparatus therein, as Well as all arts of the apparatus coming in contact wit the beverage, may be easily accessible for cleaning. To this end, the base of the urn proper, designated by reference character' 43, is formed, preferably, of av separate casting of suitable acid resisting metal and is supported upon the base plate 42 by a plurality of legs. This casting is shown in the top plan view in Fig. 3 and in section in Fig. 4. The supporting legs 44, and 46 are of special construction for the purpose of providing inlet and outlet passages for the circulating temperature control fluid and a passageway for the introduction into the dispensing urn of. the beverage to be dispensed therefrom.` To that end each of the legs 44, 45 and 45 are provided with enlarged radially extending foot portions, as clearly shown by the drawings, adapted to rest upon the base plate 42, and each of the legs have longitudinal openings extending throughout their lengths, these openings extending also into f' rtoot pieces, and in the foot pieces the we n gs being somewhat enlarged to receive the upper extremities of not only the beverage supply pipe which is connected with .ne lopening in the lower end of the leg 46, but the corresponding openings the legs 44 and 45 are connected with the respective inlet and outlet pipes 47 and 48 of the temperature regulating or refrigerating system to be presently described. At their upper extremities cach ot the supporting legs 44, 45 and 46 are expanded to furnish suitable supporting and bracing contact"\\fith the base plate of the dispensing urn. The plate 43 is provided on the top side thereof with a depression, as 1ndicated at 48, 1n the form of a segment of a sphere, which is in the nature of a sump and leading from the bottom of the same I provide one or more radially extending con duits castV in the body of the plate and terminating in the radially and horizontally extending draw-off cock or faucet ports 49 and 50.

There may obviously be any number of such i draw-oft' cocks, two being shown in the presen t embodiment ofthe invention. The upper extremities of the support-ing portions of the legs 44, 45 and 46 may be extended radially..

forming a continuation of the opening in the* brine inlet pipe 47 extending through the leg 45 and designated in Fig. 4 by the reference character 45, coincides with an opening 45b extending vertically a short distance and thence horizontally and being tapped into the i vertical brine inlet pipe 5l, which latter is provided intermediate its ends with a peripheral shoulder 52 and having its lower end passing through an orifice in the plate 43 and a corresponding orifice in the upper and inwardly projecting support atl the upper end ot the leg 45, and being threaded on its extreme lower end to receive a threaded clamping nut 53. The legs may be further strengthened in their connection with the plate byV passing suitable machine screws through perforations in spaced ears 54 formed at the top extremities of these legs. The inlet pipe 5l, for the refrigerating fluid which enters through the passageway 45b formed in the leg 45, is shown in section in Fig. 4, and passes thence through the passageway cast in the plate 43 enters the inlet pipe 51 for the refrigerating fluid through the orifice 54 in the pipe and when in use for circulating the temperature regulating fluid the lower end of the pipe 5l may be closed by a removable plug inserted in the screw threaded portion designated by reference character 55.

The discharge pipe for the temperature regulating fluid which4 conducts the fluid in the Adownward direction, as indicated by the arrows, is constructed precisely like the pipe 51 heretofore referred to as connected with the inlet forthe temperature regulating fluid in the leg and lit is designated v.by the saine reference character, being providedwitli the'.

culatory system intended to admit temperature regulating fluid to the interior of the dispensing urn for the purpose of modifying or controlling the temperature of liquids bef ing dispensed therefrom and temporarily stored therein for dispensin briey and partially described, the tempera.

g, as heretofore ture regulated fluid being admitted through the inlet pipe 51 into a closed compartment formed by the aforesaid circular plate 57, which h an upstanding peripheral flange 78 adapted to receive a cylindrical member 79, the walls of which are imperforate, but which have an upper end closed by a header plate 80. Liquids to be dispensed being admitted to the interior of the dispensing urn through the pipe lines 37 and the passageway through the'leg 46 are discharged by the angular noz- Zle 58 at the bottom of the dispensing urn on the interior thereof in such a manner as to have a circumferential motion around the interior of the urn, thus tending to stir or agitate the liquid being dispensed, which is advantageous, particularly Where liquids like vfruit juices are being passed through the apparatus. The temperature regulating fluid, as for example, the fluid from the refrigerating unit, will enter the dispensing urn through the duct au in leg 45 and thence through the lateral duct 451? and the orifice 54 and upwardly through the interior of the short pipe 51 to the interior of the cylinder 79.

The cylinder 79 may be of metal, glass or other suitable li uid retaining material and the effect of circulation of the temperature i .regulating 4fluid will be to distribute the same throughout the interior of the chamber 79 and hence impart the temperature thereof to the liquid surrounding the chamber 79, which latter is the liquid to be dispensed. The temperature regulating fluid being admitted through the bottom plate 57 is afforded opportunity for thorough intermiXing while in the cylinder 79 by reason of the fact that the discharge orifice is located near the top of the cylinder and consists of an ustanding pipe 81 which is a continuation of the return pipe 51 for the temperature controlling fluid heretofore referred to. The pipe 81 is open at its upper extremity, the open end thereof being located a short distance, as shown in F ig. 2, below the underside of the top header plate 80.

I nd that the efciency of the temperature controlling apparatus may be greatly increased by perforating the top and bottom plates and 57, respectively, and inserting therein a plurality of tubular pipes 82 similar to the flues of a boiler used in steam genA eration or water heating. Such pipes or tubes being open on their interiors at both ends, afford means for the downward passage therethrough in the direction indicated by the double-headed arrows of the liquid being dispensed from the apparatus. he cooling efficiency of the apparatus will depend somewhat upon the number of such vertical passages and will depend somewhat upon the size of the apparatus employed, and the character of the liquid being dispensed, as well as upon t-he character of the temperature controlling fluid employed in the system. With so much of a description of the apparatus as has been given, I will now refer to its preferred mode of operation interspersing further descriptive mat-ter with respect to certain parts not already detailed,

Assuming that the apparatus as shown in assembled relation, for example, in Fig. l and detailed in the accompanying drawings, installed, as shown for dispensing fruit jruces, the operator will cause a proper and desired mixture of fruit uices to be prepared within the interior of one of the tanks 12, 13. is for example, the tank 13, to which the motor driven stirrer is shown applied with the liquid to be dispensed in this tank 13, when the automatic control 22 for the motor 21 is in condition for predetermined intermittent operation, the motor will, at predetermined intervals operate the stirrer shaft 19 and the blades 2O thereon to thoroughly mix the liquid to be dispensed. it the same time the operator will admit, through the pipe 30 past the valve 32 and through pipes 36 and 37, a sufficient amount of fluid to fill the dispensing urn, such fluid or fruit `iuice passing, as before described, through the passageway in the leg 46 of the urn with a centrifugal or whirling motion into the bottom of the dispensing liquid compartment in the urn. Entrapped air may be exhausted from the dispensing urn in the initial filling operation as by opening one or more of the indicated faucets on the urn to permit entrapped air to escape until the urn is seen to be filled with the fluid to be dispensed. lVhen fruit juices, as for example, the juice of oranges or a miirture of fruit juices and various avoring ma terials with other liquids such as water and the like are being dispensed, it is usually desired to serve or dispense such fluids in a comparatively cool or chilled condition. In order that the temperature controlling fiuid to be admitted through the temperature controlling or frigerating system shall be of the desired temperature, l may, with my apparatus, employ any of the common and well known resor unit and 86 anexpansion tank'.

lAssuming thatjthe operator lhas onegor both ofthe storage .tanks12 and 18 charged with fluid fruit juicesor other desired beverages to be dispensed, the same being sus-l iceptible to periodic stirring .actions y by theV electrically voperated stirrerV described, and assuming that the 'beverage dispensingv urn has kbeen, lled by allowing the beverageto 1 flow thereinto, which, in the case'of the bev'- i erage within the storage tank 13 would .be

accomplished by openingthe valve 32 ytothe position shown inthe drawing,Fig.-1, the

operator, with the valve 32 open, would then be in position to begin dispensing beverages from the dispensing urn.

If the dispensing device shall have the beverage containing compartments thereof made of glass or other transparent material, beverage such as orange juice will be plainly visible therein, and with the r'efrigerating apparatus briefly described, the temperature of the `beverage within the mixing tanks as well as within the beverage. dispensing urn may be maintained at a desired and uniform temperature. bviously, the withdrawal cocks 49 and 50, which are shown as hand controlled, might be of any desired construction to permit the withdrawal from the interior of the dispensing urn of the cool beve-rage contained therein. However, these dispensing Asystems are usually in the care of or under the immediate control of sales persons, and in order that there may be an automatic check upon the withdrawals or sales of beverages, it is an important feature of my invention that l have provided in 'connection with the draw-off devices on my dispensing urn means whereby the operator will aut-omatically record a record of lbeverage withdrawals orservings, which is usually done by means of cups or tumblers of glass or analogous material. Y Such mechanism and further important details of my beverage dispensing urn will now be described.

Reference has heretofore been made to the agitation or swirling motion produced in the beverage upon its being discharged into the compartment Within the dispensing urn comprising the space between the cylindrical wall of the temperature controlling devices and the outer wall 61 of the urn, which space is designated generally by the reference character 115. This action is further accelerated and intermingling of incoming portions of the beverage with portions that have been submitted to the temperature regulating media prevented by means of a cylindrical band or closure member 11G which is detachably placed withinthe dispensing urn, being in the form of a cylinder open at both ends and of asize adapted to telescope or fit closely aroundthe cylindrical plate 57. Therefore, when this band 116 is in the position indicated in F ig. 4, incoming beverage must pass vertically upward through the compartment 115 to the top of the urn and-thence downwardly through the tubes or flues 82 whereit will be cooled in its passage and discharged into the compartment below the plate 57 in a modified condition with respect to temperature without mingling with the incoming and untreated currents of beverage. The

bottom plate 43 of the dispensing urn is provided with radially extending ducts 117, 118 which communicate with the sump or depressed portion 48 in the bottom of the urn.

The material aroundsaid ducts 117, 11S being radially extended on the outside of the urn in the manner illustrated in Figs. 1, 2, 3 and 4 forming the aforesaid spigots or draw-off faucets 49 and 50. The faucets or draw-E cocks 49 and 50 are identical in construction, the tubular portion thereof being expanded or thickened into a spherical like form as designated at 119. llor sanitary purposes in cleansing the draw-oil" cock, as in all of the other pipe sections of my system to be hereinafter more' specifically referred to, I prefer to close the outer extremity of the body of the faucet by a threaded hand operated plug designated by the reference character 120, which is screw threaded into the end of the pipe. Near the outer e:- tremity is provided a downwardly extending nipple or spout 121 for discharging beverage therefrom, and the passageway 117 is controlled by a rotary valve member in the form of a frustum of a cone designated at 122 having a vertical stem 123 passing through an opening on the upper side of the spherical portion of the casing and being threaded at its upper extremity and provided with a nut 124 for retaining a spring 125 therebetween and between a washerI 126 which is inserted between the spring and the casing to protect the end of the spring against friction or abrasion during the operation of the faucet. The projecting upper end of the valve is covered by an internally threaded cap co-operating with a threaded portion ofthe casingindicated at 127. The valve being of frusto-conical form under the action of the spring 125 will maintain its seat and is provided with a lateral opening 128 to register with the duct 117 to open the faucet. rlfhe means for operating the faucet valve 122 and controlling the withdrawal of beverage from the urn through the discharge nozzle or spout 121 is one of the important features of my invention, this being connected with my automatic recording device, which will now be described with reference to the structure shown in Fi gs. 1, 2, 3, 4 and 5 and shown in greater detail in Figs. 6 to 10 inclusive.

Obviously, in connection with the dispensing device of the described character the number of draw-off cocks or spigots may be varied within certain limits to accommodate one or more operators in making use of the same urn, two such units being shown in the drawings in my present embodiment of the invention, and since the mechanism associated with each of the draw-off cocks 49 and 50 is identical with respect to the' automatic interlocking and recording features, it will be understood that in describing such mechanism as connected with the draw-off cock 49, it will apply equally to the mechanism associated with the companion draw-oil' cock 50 and in each case the same reference characters will be employed. ln the dispensing urn employed in my preferred system as shown in thedrawings, thevglass tumbler or.

slot, contact with an angular projection 157 jecting branchin theform 4of a pawl 160 (see Fig.v 6). As shown in Fig: 6 when the stem` with thedisc 156. of atumbler or fglassis inserted, the iirst action of the periphery of the glass base is to engage the projection 157 and oscillate the arm 158 on its pivot against the action of the tension spring 161 to release the paWl 160 from the ledge or projecting portion 162 on the segmental plate 151, thus bringing the lever 158 and the pavvl 160 into the position shown in Fig. 6 with the stein and base of the glass all the Way into the slot. It Will be seen that as long as the paWl 160 is in engagement with the projecting portion 162 on the disc 151 the tubular member 140 and consequently the faucet valve 122 will be locked in closed positionas shown for eX- ample, in Fig. 4, With the drip pan 148 in position underneath the spigot so that any beverage dropped from the faucet Would find its Way through the openings into the tubular member 140 and drain thence back into the system or into a vessel for Waste as desired.

With the stem of the glass or tumbler in the position shown in Fig. 6, however, the faucet Will be released so that the operator by grasping the actuating arm 145 may open the valve. However, the rotation of the segmental disc 151 connected with the faucet and the tubularmember 140 in the clock-Wise direction to open the valve of the faucet will bring the parts also into the position in Which the disc 151 and the oscillating locking member 152 with its arm 155 are to be seen in Fig. 6. In other Words, when the disc 151 rotates in tne clock-Wise direction from the position of Fig. 6 to the position of Fig. 7 the slot 163 in the periphery of the disc Which engages the pin 154 on the heel of the locking arm 152 as shown in Fig. 7 Will oscillate the arm to the position shown in Fig. 6, causing the locking projection 155 to pass through the registering openings 164 and 165 on the opposite sides of the slot 137 in the casing and thus effectually locking the stem of the tumbler 156 into the slot 137 of the casing 130. This oscillation of the plate 151 Will bring the projection 166 against the iixed post 1.67 aiiixed to the top plate of the casing as a stop. The oscillation of the locking finger 155 to its tumbler locking position Will at the same time cause the cam surface-168 thereon to engage pin 169 on thefree end of r parting a portion of a cycle of movement to the count-ing device to be completed on the Withdrawal of the glass or tumbler for the purpose of indicating the dispensing of one unit or tumbler full of the beverage. The return of the lever 135 to the normal position shown in Fig. '7 and the complet-ion of the cycle of counting movement of the recording device 131 will obviously be completed When the tension spring 170 is permitted to return the lever 135 to the position shown in Fig. 7

upon the retraction of the locking finger 155, permitting the Withdrawal of the glass or tumbler and the service of the beverage Withdrawn and contained therein.

Thus, from the described construction and operation of the dispensing and recording mechanism, it Will be seen that the draw-off valve 122 will be normally in the closed position as shown in Fig. 4 with the position of the tubular member 140 and parts carried thereby in such position that any drip Will be collected in the pan 148 and drained therefrom through the tube 140, and that when the attendant desires to dispense from either of the cocks or faucets a tumbler full or portion of beverage to a customer, finding the position of the dispensing apparatus described in the positions of the parts shown in Figs. 4 and 7, for example, he will find the actuating arm 145 of the draw-off cock or faucet loclred against further Withdrawal of beverage until he frees the cam disc 151 to unlock the mechanism, Which will be done by inserting the stem and passing the tumbler into the slotted portions of the casing 130 to the position of the parts shown in Fig. 6, which Will result in the disc on the base of the tumbler operating the paWl 160 to free the disc and t-he draw-off faucet lever, Which will permit him to operate the lever or actuating arm 145 as soon as the device is unlocked and to start the flow of the beverage through the perforation 128 in the faucet valve 122, the turning of the valve through approximately ninety degrees of movement operating also to Withdraw the arm 147 and cup 148 to permit the beverage to flow into the tumbler placed directly beneath the spout 121 of either faucet, as desired.

Obviously, nothing Will be required to compel the attendant to lill the glass or tumbler, since that Will be checked by the customer and when the glass is full it can not be Withdrawn Without closing the valve of the faucet to the normal closed position shown in Fig. 4, whereupon he may Withdraw the glass due to the synchronous Withdrawal of the locking finger 155 from the slot accommodating the stem of the tumbler. This completion `of the cycle of movement of inserting and filling the tumbler and withdrawing the same will result in completing the cycle of movement to record the operation, indicating one additional dispensing unit added to the total on the recording device 131, and from which it Will be seen that any insertion of the dispensing tumbler followed by opening and closing the valve Will result in recording the same and that the draw-olf faucets or cocks Will be locked at all times against opening Without the insertion of the tumbler thereby insuring proper insertion and recording of each individual service, thus furnishing a positive check upon the Work and report of the attendant inser'vi'ngifrorn each'faucetl ofthe' dispensing ,device-1fk Y f Y e fr Another important vfeature ot my inven-v tion consists 1n certain `improved details of .construction in my system for conveying beverages to be kdispensed from the' storage and mixing tanks 12 and 13 to 4andth'roughf the' dispensing urn. Since one oi'f'the importantfu'sesto Which lmy system is adapted orfsuccesstul use is in dispensing fruit bevera-gels such vas thejuice of oranges'and .the l1ke,-it'1srof the utmostlnnportance that all 1 portions'ofthe connecting pipe lines andconfv-eying 'ductsitro'm the receptacles-'.112 and 13 to thenipples y121 of the f faucetsordravvfv on cocks be readilyaccessible torthorough 'cleaning' andi 1scrubbing l thereof-v fin .oroler` tovinsurev periectsa'nit'ation and avoid;

order to Vjclain-p the pipes and iittings to* gether into a' liquid-tight relation I havefpro? Y vi'deda special clamping glandular nut shown inv Figs. '15 'andl17`and designated generally by 1reference character 192. yThis* is'in the Y form` ofl a Vcup or .internally'fthreadednut,

y This glandular knut 192'has an openingor c' 'perforation in thebottom thereof .opposite theinternally'threaded end of a size approximately registering with the external diameter ofthe pipe, and when it is' screwed into position on the nipple offthetting, it may f be clamped around theV pipe in alloelred and substantially liquid-tight relation thereto by` reason'of the radial slots 194 Which separate the two-pairs of perforated ears 195 extending radially on opposite sides of the pipe opening. The perforations in these in at least one of each pair are threaded to take the clamping screws 196 by which this split portion of the glandular clamping nut 192 may be efectually clamped in position von the pipe and the saine securely locked in relation to the fitting.

This form of pipe connection is adaptable not only to the angular fittings but to the nipples ofthe casing of the beverage cocks 31 and 32 controlling the beveragel lines as shown in Fig. 1. The details of these beverage cocks 31 and 32 are shown in Figs. 14 and 15, the reference character 200vbeing used to designate specifically the casing which will be provided with a special form of conical perforated rotary valve 201 formed like the fitting casing of non-corrosive metal and with an operating handle 202, being held in position in its conical seat by the washer 203 on the stem at the lower end of the valve and retained in liquid-tight position by means of a compression spring 204 and adjusting nut 205. The pin 206 serving in conjunction with ledges 20T, 208 formed on the casing 200 as stops to limit the movement of the valve in either of its opened or closed positions of adjustment.

In Figs. 11, 12 and 13 I have shown the details of a form of sylphon valve control for use in temperature regulating system as shown in Fig. 1, this being designated generally in Fig. 1 by the reference character 89 and inserted in the return pipe system between the dispensing urn and the expansion tank 86. The casing 89, as shown in detail in the sectional view Fig. 11, is preferably provided of two parts or chambers 210, 211,

the former being provided with a threaded nipple 212 for receiving the return pipe 48 conduct-ing the temperature regulating fluid from the dispensing urn. Likewise, the chamber 211 is provided with a threaded nipple 213 for receiving the threaded end of the pipe 90 leading directly to the expansion tank. 214 designates a flexible metallic chamber of the common sylphon type made .of copper or other suitable flexible material, being clamped at one end as indicated at 215 to the end walls of the casing 210 and supporting at its opposite extremity one end 4of a stem'216 of a valve 217. The end of the compartment 210 at the free* end of the sylphon device is closed by a partition that may be threaded or otherwise secured to the compartment 210.v and the compartments 210, 211 are assembled as shown in Fig. 11, this partition serving as an inner wall for divide ing the two. compartments and being perforated permits the passage therethrough of the stem 216 of the valve and permitting the valve 217 to seat on the Asurface of the partition on the inside ofthe compartment 211.

This partition is designated by reference` character 218 and it is shown in detail in Fig. 13, the central perforation for the valve stem 216 being designated by reference character 219. rlhe latter issurrounded by a plurality of space-d perforations 220, all of which are adapted to be closed by the seating of the valve 21? upon this ,partition in the manner illustrated in Fig. 11. The free end of the valve stem 216 is passed into a glandular chamber 221 formed in the outer wall of the casing 211, and the outer end of the valve stem is engaged by a compression spring 222, adjustable by means of a threaded support 223 having a-portion accessible for operating it on the exterior of the gland and being adapted to be locked into position by a locking nut threaded to the externally threaded periphery thereof, designated by reference character 224. A peripheral glandular compartment 225 is provided between the locking member 224 and the casing for the use of a flexible gasket yto insure a liquid-tight connection. 226 and 22C(- are screws used in locking the compartments of the casing 89 together. The sylphon valve 214 is of the type commonly adapted to be affected by changes in temperature and upon the expansion thereof it will lift the valve 217 from its seat against the action of the spring 222 and permit the passage of the temperature regulating fluid on its return from the dispensing device through the nipple 212 and the perforations 220 in the partition adjacent the valve seat and through the nipple 213 into the expansion tank. The reference character 228 designates a normally open port in the partition permitting the passage of a minimum amount of cooling iiuid at all times regardless of the temperature thereof.

From the previous description of the temperature regulating system, it will be noted that from the pump 88 which circulates the temperature regulating tiuid there are two pipe systems employed, the one first described leading to the storage units 10 and 11 and the other, the pipe system last described, leading from the pump to the dispensing unit or urn 40 with the return line back to the expansion tank 86 controlled by the temperature control sylphon valve just described. In Fig. 1 I have shown the preferred arrangement of the apparatus, from which it will be .seen that chiefly in the supply and return pipe lines 97 and 106 and the by-pass extensions 108 and 110, I maintain a hydro-static column of liquid free at all times to be circulated by the pump 88, which is normally intended to be operated continuously while beverage is contained in the storage tanks or in other parts of the system. The effect of this column of liquid is obviously to result in an amount of pressure being exerted upon the refrigerating pipe system leading to, through and fromr thedisperlsing unit 0r urn, It will furthermore be seen that the nfiioveinent" ofY the temperature-regulating v yluidthrough this pipe circuit and through the' urnvvillbedeterinined'by the sylphon valve which will lopen .and close lunder the' controloftlie 'temperature of the liquidl in v the system.
